Answer:
Mechanical energy = 145 Joules
Explanation:
Given the following data;
Kinetic energy = 115J
Gravitational Potential energy = 30J
To find the mechanical energy;
Mechanical energy = kinetic energy + gravitational potential energy
Substituting into the equation, we have
Mechanical energy = 115 + 30
<em>Mechanical energy = 145 Joules. </em>
Mechanical energy can be defined as the ability (capacity) to do work. The two (2) main types of mechanical energy are;
<em>a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.</em>
<em>b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.</em>
I’m not sure but it might be B.
It’s true By the end of the 19th century, the Western powers and Japan had forced China’s ruling Qing dynasty to accept wide foreign control over the country’s economic affairs. In the Opium Wars (1839-42, 1856-60), popular rebellions and the Sino-Japanese War (1894-95), China had fought to resist the foreigners, but it lacked a modernized military and suffered millions of casualties.

For example, when a government imposes an import tariff, it adds to the cost of importing the specified goods or services The additional marginal cost added by the tariff discourages imports, thus affecting the balance of trade.
